Molding of circular articles or palterns.--If circular articles or patterns are to be molded, a chaiu-pulley,V, is supported upon the table so as to turn about the axis of the screw I, and the flask or molding-box rests upon a twopart auxiliary table or support, S S, which is connected with the chain-pulley V by pins .9.

The 5 flexible rammer enables small objects or patterns to be molded without shifting the flask or molding-box, the workman moving the head of the rammer as may be required. It is also advantageous in molding conical objects, as it enables the proper inclination to be given to the rammer.

Apparatus with sand-distributer sepm'atefi'om rammer.-For molding patterns which require a large quantity of sand a difficulty or incon- I venience is experienced in the use of a rammer made tubular to serve as the sand-distributer, since this, being of metal, and required to be strong to resist the impact of the rammer on the sand, is, when of the proper size, heavier than is desirable. To overcome this difficulty a separate sand-distributer surrounding the rammer is employed. With this construction, as with the tubular rammer, the sand is compacted in the flask as it is delivered from the 25 hopper. The rammer is or may be solid, and can be formed of a bar adapted to withstand the longitudinal-compression strains to which it is subjected, and flexible in a lateral direction, or rigid, as-may be preferred. The sand- 6 distributer is preferably formed of rubber, leather, or other flexible material, and it can be attached to the rammer, so as to rise and fall with it, or it can be attached to a stationary part of the machine. In either case it accompanies the rammer or the head thereof in its lateral or translatory movement.

In Fig. 10 the sand-distributer A is shown suspended from a plate, K, itself secured to the hanging bracket K, carried by the piece or box F. The upper partis widened to form the hopper B. The rammer extends through the hopper and moves in guides in the piece or box F, and is reciprocated through the lever 0 by means of the cams O on the shaft g, which as shown is the main or power shaft. P is a flywheel on this shaft q.

The sand can be introduced directly into the hopper by the workman, or by mechanical means; but it is preferred to introduce it through the sieve L, to which a reciprocating movement is imparted in any suitable way, as

by means of a rod or pitman, l jointed at one end to the sieve and encircling at the other an eccentric-pin, l, projecting from the face of a disk carried by the shaft 1 This disk is connected with the shaft by clutch mechanism, so that it can be disengaged when it is desired to stop the sieve L. The shaft Pcan be driven from the shaft g.

In the apparatus shown inFig. 10 the mechanlsm for operating the table carrying the flask or molding-box is also simplified.

The plate H is supported by the screw I. which passes through the chair or support I and engages with a nut formed by the center of the chain-pulley V. Motion is communicated to the chain-pulley V from the cam-shaft g by means of the belt p running upon conepulleys s on the shafts q and W, the bevelgears on n, the vertical shaft t, the chain-pul- 7o ley V and the endless chain T.

It is obvious that the gearing is so calculated as to cause the table H and flask to descend the required distance for each revolution of the cam-shaft. V.

The dimensions, proportions, forms, andmaterials of the various parts can be modified without departing from the spirit of the invention. Accessory parts and the gearing or devices for transmitting motion can be varied as desired.
